In operation, the Cat excavator usually operates at a normal temperature range between 80°C and 95°C, which is a key factor in ensuring the stability of the machine's performance and extending its useful life.When the engine temperature of the Cat excavator exceeds this standard range, especially when 100°C is reached or exceeded, we can assume that the device is in a high temperature state.High temperatures may cause not only the deterioration of oils, the boiling of cooling fluids, but also early wear and even damage to the interior parts of the engine.In order to prevent and resolve the high temperature of the Cat excavator, it is necessary, first, to periodically inspect and replace the cooling fluids to ensure the proper functioning of the radiator system; secondly, to pay close attention to the real-time temperature shown on the operating dashboard and to stop checking the engine as soon as an abnormal increase is observed; furthermore, daily maintenance of the engine, such as cleaning up carbon and maintaining good lubricants, should not be overlooked.In summary, it is important for Cat excavator users to clearly identify temperatures above 100°C as high engine temperatures, to respond in a timely manner and effectively avoid all types of mechanical malfunctions caused by high temperatures and to ensure that excavators operate efficiently and safely.
